In　the　context　of　the　rapid　development　of　co-simulation,　this　paper　designs　and　implements　an　HVAC　laboratory　based　on　the　co-simulation　research,　which　realizes　the　co-simulation　of　device　controller　and　FMU　simulation　model　through　the　combination　of　reality　and　virtual,　and　establishes　a　virtual　simulation　laboratory　to　test　the　performance　of　device　controller　and　assist　in　learning　HVAC　principles.　In　this　paper,　the　author　use　LabVIEW　language　to　focus　on　the　data　channel　of　co-simulation,　data　integration　and　data　storage　after　the　combination　of　reality　and　imagination,　so　that　the　users　realize　the　influence　of　controller　input　parameters　on　the　model　and　the　influence　of　model　output　parameters　on　the　controller　in　the　interface　and　realize　dynamic　adjustment.　©　2023　IEEE.
